1 The Partner External Module Program June 16 th, 2010 ScilabTec - Workshop 3 Contribute to Scilab

2 2 The Partner External Modules Program (PEM)

3 Outline Goals of the program Examples of available PEMS How to download and use modules Services and benefits for developers Who have already joined the program How to join the program

4 Goals of the program To give to users the maximum of possibilities and functionalities with Scilab and Xcos. To offer complementary modules selected by their quality, fiability and ease of implementation and use. To have the most complete tools in mathematics computation and simulation worlds To allow external people to develop modules in adequation with their needs.

5 Examples of available PEMS Space Mission Analysis and Design Plant Modelling and simulation Applied Economy, Economic Forecast 5

6 How to download and use PEM 2 possibilities : Via an embedded client in Scilab, named ATOMS. This client gives to users the opportunity to easily install and uninstall modules. Via the website : The user can explore the complete list of External Modules The user can post some questions about module use or bugs

7 Services and benefits for developers Deposit of the code on an official repository via the dedicated website. Via this Website : Managing of the versioning of the module Access to download statistics Possibility to answer to user s questions. 10 hours of free support by the Scilab Consortium R&D team.

8 Who have already joined the program We have 4 types of partners : Companies: CNES Colleges and universities: UTC, Luxembourg University Academics: LIAMA, INRIA Private contributors: Grocer Today, 7 PEM, only for Scilab.

9 How to join the program Send an to or By the way, complete and sign the program agreement.

13 3 What is a Scilab Contributor?

14 Two kinds of contributors External contributions Core contributors 4

15 External Contributor PEM, external modules, documentations, etc. No constraint from the Scilab Consortium: Free on their development choices, license aspects, website... Roadmap and release schedule left to the contributor(s)... 5

16 Help for External Contributor The Scilab Consortium provides: Forge ( development platform with VCS (git, svn), bug tracker, etc Module template (toolbox_skeleton) Developer mailing list ATOMS: packaging system (if the module follows some basic rules) Code review ( 6

17 Core Contributor Has the same rights, permissions and constraints as any Consortium developer Work on the base code of Scilab 7

18 Core Contributor Constraints Respect the current architecture, paths, naming... Coding style (Scilab, C/C++ & Java) Respect the procedures (Code Review) Scilab Enhancement Proposal (SEP) 8

19 Help for Core Contributor Easy access to the Consortium R&D team through a contact ''support'' Help with our various tools Access to all Scilab's tools with advanced permissions (code review, bug tracker, task manager) 9

20 My Role Interface (advanced questions, advices,etc) Provide information about the release schedules New features integrations Facilitate communications (Scilab R&D team <=> contributor) 10

21 Requirements Being reactive Answer to all questions Smooth the ''distant working issues'' 11

22 12 How to become a Scilab contributor?

23 Watch Most of the services are public Bug tracker Git Code Review Translation interface Communication vectors 13

24 Ask & Start Do not hesitate to ask questions on the dev mailinst list Identify on which part you could help Start easy Send the modifications (patches) on the bug tracker or the mailing list Request to become an official contributor 14

25 Be a Scilab's contributor June, 17 th,

26 Presentation Calixte Denizet Maths teacher in Brittany Developer Author of Scilab's toolbox : SciMax and Overload, few contributions in Scilab to render LaTeX strings (graphics, export and help) and lastly commit of a refactorization of the Editor. 16

27 17 What is my job?

28 External contributor I began my career of Scilab's contributor in writing SciMax (an interface between the CAS Maxima and Scilab) and Overload (to overload macros). I worked alone and learnt a part of the sourcecode. Few months ago, I put my work on the Scilab's Forge with a GIT repository. 18

29 My first patch I proposed my first patch to display MathML in graphics Consequences : Acceptance of my patch Development of JLaTeXMath on a Sylvestre's idea. A proposition to be an official contributor 19

30 Core contributor My first experiment with GIT : It 's easy : git add && git commit && git push... It's not easy : must push the files in the right order... Difficulties to communicate with people you don't see. First steps with the codereview and git were difficult. 20

31 I'm not alone Sylvestre is always here. Pierre M. is very patient and is able to explain several times the same thing about the git philosophy... Vincent helped me in developing GUI. Bugzilla... 21

32 Satisfaction Contribute to a free project such as Scilab Have the possibility to code in different languages Have the ideas of other people 22
